CROSS-REFERENCE TO RELATED APPLICATIONS

This disclosure claims the benefit of and priority to U.S. ProvisionalPatent Application No. 62/119,569 filed on Feb. 23, 3015, the entirecontents of which are incorporated by reference herein.

BACKGROUND 1. Technical Field

Embodiments of this disclosure relate to remote control devicesgenerally, more particularly to remotely controlled flying devices.

2. Background of Related Art

Remote control flying devices are increasing in popularity. Remotecontrol flying devices typically comprise propellers that are driven byelectric motors. Actuators, such as servo motors, control flyingcharacteristics, such as direction, altitude, and speed. Drones wereoriginally developed for use by the military in the context of specialoperations. The technology has spread to civilian applications such aspolicing, firefighting, and security. Many are predicting that thedeveloped world is on the cusp of a dramatic revolution in the use ofdrones for non-governmental use. Quartz (www.qz.com) published anarticle in January 2013 titled “[t]he private drone industry is likeApple in 1984.”

There are good reasons to conclude that drone technology may soon impactthe daily lives of everyday consumers. Amazon CEO Jeff Bezos dominatedthe headlines during the busy Christmas shopping season of 2013 when heannounced that Amazon was testing drone technology as a potentialdelivery system for some Amazon products. In February 2014, thewww.aviationpros.com website in February 2014 publicized two reportspredicting a global drone market of $8.35 billion by 2018 and $14.7billion by 2023. In response to the anticipated wide-spread adoption ofdrone technology, the Federal Aviation Administration (“FAA”) issued a“road map” on Nov. 7, 2013 that identified technical, regulatory, andprocedural issues that would need to be overcome for the widespreadintegration of drones into commercial airspace. Numerous statelegislatures have enacted or are considering the enactment of lawsaddressing privacy and safety concerns pertaining to the proper use ofdrones.

In anticipation of burgeoning governmental and private markets fordrones, there are significant ongoing efforts to improve dronetechnology in certain respects. In the past, such devices have beenprimarily used as toys, but there is increasing interest in the use ofsuch devices for delivering payloads, such as packages, or for utilityfunctions, such as photography. A problem associated with the use ofpropeller driven remote control devices is the danger of contact of themotor driven propellers with humans, animals, or other objects. Rapidlyspinning motor driven propellers can cause serious injury to humans,animals and property. Further, motor driven propellers can becomeentangled in vegetation or other objects, causing loss of the remotecontrol device, or disabling or damaging the remote control device.

The word“example” may be used interchangeably with the term “exemplary.”Moreover, certain terminology is used in the following description forconvenience only and is not limiting. For example, the words “right,”“left,” “top,” “bottom,” “upper,” “lower,” “inner” and “outer” designatedirections in the drawings to which reference is made. The word “a” isdefined to mean “at least one.” The terminology includes the words abovespecifically mentioned, derivatives thereof, and words of similarimport.

FIG. 1 shows an embodiment of the housing for a remote controlled flyingdevice according to the disclosure. In an embodiment, the housing orbody can be a unibody, which may be formed in two portions or parts thatmay be separated for access to the interior of the housing. The devicemay have a top portion 2 that is mounted to a bottom portion 4.

As shown in FIG. 5, the interior surfaces of the top portion and bottomportion are spaced apart. Electrical, mechanical and electro-mechanicalparts of the device can be positioned within the interior of thehousing. As shown in FIG. 4, a plurality of motor driven propellers 6,in this case, six (6) propellers can be mounted in the interior of thehousing. Also mounted in the interior of the housing can be operationaldevices 16, such as radio receivers, for remote control of the device,and navigational controls and other devices as required. In certainembodiments, an interior wall can include individual levels, recesses,platforms or bridges to accommodate spaces for mounting motors,batteries, flight control boards, speed controls and/or any othersuitable components, positioned at a desired height or plane relative toallowable interior space. These areas may be formed, such as by molding,milling or cutting, into the interior walls, so that body and interiormounting points are one piece in a unibody configuration. One or moreportions of the housing may be additively manufactured (e.g., 3Dprinting). Motors may be mounted on columns 11 of varying height so asto accommodate larger, overlapping propellers within the allotted space.Propeller tips may overlap neighboring propeller tips on differentplanes. In certain embodiments, propeller tips may remain in the sameplane such that propeller tips do not overlap.

Actuators for the navigational controls may also be mounted within theinterior of the housing, and/or the exterior of the housing. Mounting ofremote control receivers, motors, and navigational control systems, suchas ailerons and rudders, and actuators devices is within the purview ofone skilled in the art of constructing remote control flying devices.

Preferably, the device does not include any interior elevator, aileronor rudder control surfaces. Directional control can be accomplished bycounter rotating motor/props and/or varying individual motor speeds. Themotors and props can control pitch, roll and yaw. One or all motors maybe mounted on tilting motor mounts to effect additional or complimentarydirectional change. Elevator, aileron and/or rudder control surfaces maybe incorporated into the exterior of the design with addition ofwinglets, vents or such.

As shown in FIG. 6, the housing can be formed so as to have continuouspores 8 in substantially all, or a majority, of the surface of thehousing. The pores allow air to flow through the housing. Mounting ofthe propellers in the interior of the housing causes air to be pulledthrough the housing by the propellers, with one side of the housingacting as an inlet. The air is exhausted through an opposite side of thehousing, acting as an outlet. For example, with the motors mounted asshown in FIG. 4, the top portion of the housing acts as an inlet, andthe bottom portion of the housing allows air to be exhausted through thepores in the bottom portion of the housing. However, in some cases, oneor more of the propellers may be reversed in direction of rotation,causing air flow through the housing to be reversed. Speed, altitude anddirection of the device may be controlled by the speed and direction ofrotation of the motors. Some motors may be mounted inverted while othersmay be mounted vertical, depending on the embodiment. Propellers andmotors may or may not be mounted and/or spaced on different plains toallow propeller tip overlap and tighter motor space geometry. This givesgreater flexibility in overall outer housing shapes, such as the dropletshape.

The pores 8 of the body that allow air to flow through the body areformed in the body, which can be a unibody construction. The body may beformed of corrugated or fluted paper, plastic, metal, carbon fiber, foamand/or other materials that will form a body surface that isaerodynamic, but which also allows air to pass through the pores formedin substantially the entire surface, or at least a majority of the bodysurface. The air passes into, and through, the interior of the body andout of the body. Corrugated construction of the body is shown in FIG. 7.

The body may be formed by machine, injection molding, or by 3D printing,for example, depending upon the material from which the body is formed.The body or unibody may be formed in desired shapes, including novelshapes, or shapes that mimic known shapes of other devices or articles.The surface of the body may be imaged with indicia, logos, or graphicdesigns, as long as the pores of the body are not obstructed.

As shown in FIG. 5, the body may have a few openings 10, 12 that arelarger than the pores (e.g., to allow griping of the housing). Theseopenings may be sufficiently small so that an average size of a hand ofan adult human cannot be inserted into the interior of the housing. Incertain embodiments, the body has no openings (other than the pores),which may improve aerodynamics.

In certain embodiments, the pores sizes can be no larger than about 40millimeters, and no smaller than about 0.5 millimeters. The pores cancover at least fifty percent of the surface of the top and fifty percentof the surface of the bottom of the housing, for example, but anysuitable arrangement, coverage area, hole size, shape, and/or pattern iscontemplated herein. For example, the pore size can change from smallerin the front (e.g., about ¼ inch), to larger in the middle portion(e.g., about ½ inch), to smaller again in the back (e.g., about ¼ inch).The change can be gradual and/or abrupt in certain embodiments.

In certain embodiments, no more than two openings larger than the poresmay be formed in the top portion of the housing, and no more than twoopenings larger than the pores may be formed in the bottom portion ofthe housing. These openings in the body may be no larger than about 150centimeters (e.g., in embodiments of the body that are sized for liftingby a single person).

The materials from which the housing is formed may have crash and impactabsorbing body properties. The body properties may be such that upondeformation due to impact, the body will not be cut or torn, and mayfurther be resilient and regain its shape after the force of impactcease, or may be easily pulled to the original shape. For this reason,forming the body of polymer or plastic is suitable in many applications.Any other suitable material is contemplated herein. The use of a bodysurface having entirely arcuate surfaces instead of sharp angles to formthe body surface may improve aerodynamics for example, however, anysuitable shape is contemplated herein.

Purposely engineered reliefs, channels, or valleys, or individual areasof thinning of material thickness on the inside of the walls of one orall parts of the unibody may form crumple zones of the body. In anembodiment, the pores defined through the surface of the top portion orbottom portion are 1.58 millimeters in diameter or width and 0.03millimeters wall thickness between adjacent pores. In certainembodiments, material can be cut, or ground out in addition to beingcreated by 3D printing. 3D printing may include any additivemanufacturing or stereolithography (SLA) technique. 3D printing refersto various processes used to synthesize a three-dimensional object. In3D printing, successive layers of material are formed under computercontrol to create an object. SLA or SL, also known as OpticalFabrication, Photo-Solidification, Solid Free-Form Fabrication, SolidImaging, Rapid Prototyping, Resin Printing, and 3D printing, may be anyform of additive manufacturing technology used for creating models,prototypes, patterns, and production parts in a layer by layer fashionusing photopolymerization, a process by which light causes chains ofmolecules to link together, forming polymers. In certain embodiments,material can be molded through a plastic injection molding technique.Plastic injection molding can include any manufacturing process forproducing parts by injecting material into a mold. Thinning and reliefdesigns allow major impact points to fold, crumple, bend or distortinwardly, so as to absorb inertia, minimize impact force and contain anddeflect inner parts from a surface of an object. Crumple zones can bedesigned to permanently distort (i.e. no spring back) without weakeningstructural integrity of a non-damaged model.

The device may be provided with an internal payload, which may beaccessed through the holes or ports 10 as shown in the top of thehousing FIG. 1, or through a removable panel 14 as shown in FIG. 8. Acargo compartment may be inserted into and mounted within the opening.The cargo compartment allows transportation by the flying device ofpayloads such as parcels, medicine, food, water, first aid supplies, aswell as sensors for data collection or photography or videography.

In certain embodiments, the device may not have an overall weight ofmore than 30 kilograms. In general, the device may have a shape and sizethat is sufficiently small that it may be lifted and carried by a humanof average size and strength but any size is contemplated herein.

FIG. 9 shows another embodiment of the device which can include a middleportion 901 that attaches to the bottom portion 4 and top portion 2. Incertain embodiments, the middle portion can act as a housing extension,creating a larger interior compartment for additional components. Bottomportion 4 and top portion 2 may attach to middle portion 901 through avariety of attachment means, including; screws, bolts, clamps, adhesivetape, snaps, magnets, and the like. Bottom portion 4 may be concave inshape and top portion 2 may be convex in shape. Middle portion 901,bottom portion 4 and top portion 2 may be configured such that whenassembled as a unitary structure, a front portion of the device is morebulbous or larger than a rear portion of the device thereby defining anoblong pear or droplet shape of the device. Middle portion 901, bottomportion 4 and top portion 2 may be constructed of carbon fiber, carbonfiber infused thermoplastic, wood infused thermoplastic, metal infusedthermoplastic, ceramic and/or ceramic infused thermoplastic. Bottomportion 4 and top portion 2 may allow for mounting of exteriorattachments including cameras, light fixtures, sensors, winglets,electronics, displays or other enhancements. Middle portion 901, bottomportion 4 and top portion 2 may vary in size and scale from palm-sizedbodies up to approximately 60 pound units. According to an embodiment,middle portion 901, bottom portion 4 and top portion 2 may be about 100to 150 centimeters in length, about 40 to 100 centimeters in width, andabout 15 to 50 centimeters in height.

The surface of the middle portion can include a plurality of pores thatare physically similar in size, shape, and spacing to that of the topportion 2 and bottom portion 4. Further, the pores can be functionallysimilar to those defined in the top portion 2 and bottom portion 4 byallowing the flow of air. It is contemplated that the middle portion 901need not have pores, and/or that the pores of the middle portion bedifferent than those on the top portion 2 and/or bottom portion 4. Poresmay be uniform or non-uniform in pattern, and the size, shape andspacing of the pores may vary from a forward portion of the device to arear portion of the device. In an embodiment, pores may be configured inan octagonal honeycomb pattern. Other shapes and patterns may includesquares, triangles, circles, hexagons, polygons, rectangles, and othergeometric or irregular shapes.

In certain embodiments, motor driven propellers 6, columns 11, and/orother operational devices 16 can be disposed on the bottom portion 4and/or the top portion 2. The bottom portion 4 can include a cargo bay903 that is either integrated as part of the bottom portion 4 duringmanufacture or incorporated after manufacture as an additionalcomponent, for example. In certain embodiments, the cargo bay 903 canopen up to the bottom of the bottom portion 903 to store or release itscontents. In an alternative embodiment, middle portion 901, bottomportion 4 and top portion 2 may be coupled around a commercialoff-the-shelf drone to encapsulate an enclosed body around the drone.

In certain embodiments, referring to FIG. 10, the middle portion 901 caninclude a support structure disposed therein. In certain embodiments,the support structure can include a K-frame 1001 (e.g., which spans theinner width of the middle portion) as shown. The K-frame 1001 caninclude any variation of symmetrical or asymmetrical intersection ofcross members spanning the width or length of the middle section.K-frame 1001 may also be configured as an X-frame or a star-shapedframe; and may be configured as a six-sided, six armed, or hexa-frame.Furthermore, the K-frame 1001 can be made of any suitable material foruse with unmanned aerial vehicles; e.g., metal, polymer, thermoplasticssuch as PLA, ABS, polypropylene, and other hybrid plastics as mentionedherein, parchment, and metal alloy.

In certain embodiments, the K-frame 1001 can be used to support one ormore motor driven propellers 6, columns 11, or other components 16 suchas controllers, electronics, GPS modules, antennas, computer boards andthe like. The motor driven propellers 6, columns 11, or other components16 can be mounted to any suitable portion of the K-frame 1001 (e.g., onthe top or bottom sides of the K-frame 1001) in any suitable manner.

The K-frame 1001 can be secured to the middle section or integrated intothe middle portion 903 itself (e.g., a 3D printed or molded middlesection with integrated K-frame for example). An assembled view of anaerial vehicle with middle portion 903 is shown in FIG. 11.

Embodiments of the housing as described above allow the aircraft tocontact humans, animals, structures, vegetation, and other objectswithout presenting a danger of physical harm, or harm to humans, animalsand structures, or to the propellers, from propeller rotation. Theenclosed body also prevents the propellers from becoming entangled invegetation. Placing propellers internal to the body of the deviceprevents the propellers from coming in contact with humans, animals,structures, vegetation and other objects. Further, by having internalpropellers, the sound signature of the device may be reduced, allowingfor more silent operation than a device having exposed propellers.

The device also may be used indoors, since there is no danger ofpropeller strikes, and the housing can be formed to be damage resistantand impact resistant. Incidental contact with humans and other objectsdoes not present a threat of injury to humans or objects from propellerstrikes. Accordingly, the device can be used to deliver payloadsindoors, particularly in warehouse and factory settings. The device maybe intercepted with bare human hands without fear of propeller strikes.
